Just a quick question. How long does a broken collar bone take to heal? 3 months back a truck backed out of a drive way in front of me. I had to lay the bike down rather than T-bone the truck. I was doing about 40 - 50 kmh. Did a slide then an endo into a ditch. I broke my collar bone, and had a few other soft tissue injuries. It is still sore and has limitations.
